The Targus TouchPen system is a stylus and a small device that clips onto the side of a laptop. That device pairs with the stylus, a digitizer pen, to fool any non-touchscreen device into thinking that it has a touchscreen. Targus claims this is the only product that will do this for non-touchscreen devices running Windows 8, but apparently they didn’t consult with E Fun first, because E Fun’s APEN Touch 8 system is essentially the exact same device, and is also going to be on display at CES.
There is one difference that you should take note of if you own a 17” laptop – the Targus device supports 17” notebooks, while the E Fun device is only good up to 15.6”. Like the E Fun device, you will need to use the stylus provided in order to actually use the touch features provided by the TouchPen system – it relies on communication between the add-on device and stylus, so using your finger won’t cut it.
As of CES, the Targus TouchPen system should be available in stores and online for about $100.
